And I know why.

Actress and mum-of-four Sadie was horrified when she discovered the junkie rocker had hidden drugs in her handbag during a group holiday.

It was in June 2005 when Sadie, Kate and Pete were on a boat owned by the father of their pal DAVINIA TAYLOR, cruising round the Med.

Yes, Newton's big exclusive is actually I Know What You Did The Summer Before Last, tacked onto a vaguely-worded guess that Frost will be pleased that Moss has dumped Pete. Hold the front page, everybody.
